DETAILED DESCRIPTION

A portion of an exemplary frame pool 100 is shown in FIGS. 1 and 2 . Theillustrative portion of the frame pool 100 includes two adjacenthorizontal frame members 6 (e.g., horizontal pipes) that cooperate toform an upper rim of the frame pool 100 and a vertical frame member 7(e.g., vertical pipe) that extends downward from the horizontal framemembers 6 to support the frame pool 100 on the ground. Although notshown in FIGS. 1 and 2 , similar frame members 6 and 7 may be providedaround the remaining perimeter of the frame pool 100. The frame pool 100may vary in size and shape. For example, the frame pool 100 may berectangular, circular, elliptical, or other suitable shapes.

Referring still to FIGS. 1 and 2 , a T-shaped joint 10 may be used toremovably couple the two adjacent horizontal frame members 6 to theadjacent vertical frame member 7. Although a single T-shaped joint 10 isshown in FIGS. 1 and 2 , similar T-shaped joints 10 may be providedaround the remaining perimeter of the frame pool 100. Each T-shapedjoint 10 illustratively includes two horizontal joint portions 1configured to couple to the horizontal frame members 6 and a verticaljoint portion 2 configured to couple to the vertical frame member 7. Toform the T-shape, the vertical joint portion 2 is centered between andperpendicular to the two horizontal joint portions 1. The orientation ofthe horizontal joint portions 1 determines the orientation of theadjacent horizontal frame members 6. In the illustrated embodiment ofFIG. 1 , for example, the horizontal joint portions 1 define an obtuseangle α therebetween, so the horizontal frame members 6 define the sameangle α therebetween. In another embodiment, the horizontal jointportions 1 may be collinear with each other, so the horizontal framemembers 6 would also be collinear with each other. In anotherembodiment, the horizontal joint portions 1 may be perpendicular to eachother, so the horizontal frame members 6 would also be perpendicular toeach other, such as along a corner of a rectangular frame pool 100.

Some or all components of the frame assembly, including the horizontalframe members 6, the vertical frame members 7, and/or the T-shapedjoints 10, may be constructed of a polymer, specifically plastic, suchas by injection molding. Compared to metallic components, the plasticcomponents may be smooth and elastic to facilitate assembly anddisassembly of the frame assembly. Also, the plastic components may bemore resistant to galling and corrosion to promote extended use. Withrespect to the T-shaped joint 10, in particular, the horizontal jointportions 1 and the vertical joint portion 2 may be integrally formed asa single piece of plastic. Alternatively, the horizontal joint portions1 and the vertical joint portion 2 may be formed as multiple pieces ofplastic and then fixedly coupled (e.g., adhered, welded) together. Theupper end of the T-shaped joint 10 may include a raised rim 22 (FIG. 3 )to give the appearance that the vertical joint portion 2 wraps aroundthe horizontal joint portions 1.

The illustrative frame pool 100 of FIG. 1 also includes a pool liner 8supported by the frame members 6 and 7 to form an interior water cavityfor swimming and/or bathing. The pool liner 8 may be wrapped and securedaround the horizontal frame member 6 to form a loop or fold 81. The fold81 of the pool liner 8 may also define a gap or hole 82 to expose theT-shaped joint 10, as described further below.

The illustrative T-shaped joint 10 is described in more detail withreference to FIGS. 3 and 4 .

The horizontal joint portions 1 of the illustrative T-shaped joint 10are configured to couple with the adjacent horizontal frame members 6(FIG. 2 ). The horizontal joint portions 1 may be configured to fitwithin the adjacent horizontal frame members 6 in a sleeved manner.Thus, the external cross-section of the horizontal joint portions 1 maymatch the internal cross-section of the horizontal frame members 6. Inthe illustrated embodiment of FIG. 3 , the external cross-section of thehorizontal joint portions 1 is generally triangular with rounded edgesto resist rotation between the horizontal joint portions 1 and thehorizontal frame members 6. It is also within the scope of the presentdisclosure for the external cross-section to be circular, rectangular,elliptical, or another suitable shape to match the internalcross-section of the horizontal frame members 6.

Each horizontal joint portion 1 of the T-shaped joint 10 includes acoupling assembly 3 for removable attachment to the adjacent horizontalframe member 6 (FIG. 2 ). As shown in FIGS. 3 and 4 , each couplingassembly 3 includes a base 31 received in the horizontal joint portion1, a helical spring 32 held in place by the base 31, and a pin 33extending radially outward (e.g., downward) through a hole 35 in thehorizontal joint portion 1. Each horizontal joint portion 1 may includean internal horizontal reinforcing rib 11 and/or an internal horizontalsupport member 5 to help support base 31 within the T-shaped joint 10.In an assembled or locked state, spring 32 may bias pin 33 radiallyoutward through hole 35 to engage a corresponding recess or hole (notshown) of the horizontal frame member 6 (FIG. 2 ). In a disassembled orunlocked state, a user may press pin 33 radially inward to compressspring 32 and disengage the horizontal frame member 6 (FIG. 2 ).

The vertical joint portion 2 of the illustrative T-shaped joint 10 isconfigured to couple with the adjacent vertical frame member 7 (FIG. 2). The vertical joint portion 2 may be configured to fit within theadjacent vertical frame member 7 in a sleeved manner. Thus, the externalcross-section of the vertical joint portion 2 may match the internalcross-section of the vertical frame member 7. In the illustratedembodiment of FIG. 3 , the external cross-section of the vertical jointportion 2 is generally triangular with rounded edges to resist rotationbetween the vertical joint portion 2 and the vertical frame member 7. Itis also within the scope of the present disclosure for the externalcross-section to be circular, rectangular, elliptical, or anothersuitable shape to match the internal cross-section of the vertical framemember 7.

The vertical joint portion 2 of the T-shaped joint 10 includes acoupling assembly 4 for removable attachment to the adjacent verticalframe member 7 (FIG. 2 ). As shown in FIGS. 3 and 4 , each couplingassembly 4 includes a base 41 received in the vertical joint portion 2,a helical spring 42 held in place by the base 41, and a pin 43 extendingradially outward (e.g., rearward) through a hole 45 in the verticaljoint portion 2. The vertical joint portion 2 may include one or moreinternal vertical reinforcing ribs 21 to help support base 41 within theT-shaped joint 10, such as by compressing fingers 46 of base 41 togetherwithin the T-shaped joint 10. In an assembled or locked state, spring 42may bias pin 43 radially outward through hole 45 to engage acorresponding recess or hole 71 of the vertical frame member 7 (FIG. 2). In a disassembled or unlocked state, a user may press pin 43 radiallyinward to compress spring 42 and disengage the hole 71 of the verticalframe member 7 (FIG. 2 ).

According to an exemplary embodiment of the present disclosure, and asshown in FIG. 4 , the size of the T-shaped joint 10 may be minimizedsuch that the size of the corresponding hole 82 in the pool liner 8(shown in phantom) may also be minimized. The small hole 82 in the poolliner 8 may improve the appearance and water containment of the framepool 100 (FIG. 1 ) while still leaving the coupling assemblies 3 and 4,specifically the pins 33 and 43 of the coupling assemblies 3 and 4,accessible for subsequent disassembly.

The width of the T-shaped joint 10 may be minimized such that the widthof the corresponding hole 82 in the pool liner 8 may also be minimized.For example, the total width W_(J1) of the T-shaped joint 10 may beabout 5 inches to about 7 inches, specifically about 5¾ inches, thewidth W_(J2) between the pins 33 of the coupling assemblies 3 may beabout 3 inches to about 5 inches, specifically about 3 13/16 inches, andthe width W_(J3) of the vertical joint portion 2 may be about 1 inchesto about 3 inches, specifically about 2⅜ inches. In the illustratedembodiment of FIG. 4 , the width W_(L) of the hole 82 in the pool liner8 is greater than both the width W_(J3) of the vertical joint portion 2and the width W_(J2) between the pins 33 to expose the pins 33 of thecoupling assemblies 3 for subsequent disassembly while being less thanthe total width W_(J1) of the T-shaped joint 10. For example, the widthW_(L) of the hole 82 in the pool liner 8 is about 3 inches to about 7inches, specifically about 4½ inches.

To help minimize the size of the T-shaped joint 10, the pins 33 of thecoupling assemblies 3 may be positioned close to the vertical jointportion 2. Due to this close positioning, the width W_(J3) of thevertical joint portion 2 may account for a majority of the width W_(J2)between the pins 33 of the coupling assemblies 3. For example, the widthW_(J3) of the vertical joint portion 2 may account for 50%, 60%, 70%,80%, or more of the width W_(J2) between the pins 33 of the couplingassemblies 3. In the illustrated embodiment of FIG. 4 , in particular,the width W_(J3) of the vertical joint portion 2 accounts for about 70%of the width W_(J2) between the pins 33 of the coupling assemblies 3.The width W_(J3) of the vertical joint portion 2 may also account for asignificant portion of the total width W_(J1) of the T-shaped joint 10.For example, the width W_(J3) of the vertical joint portion 2 mayaccount for 40%, 50%, 60%, 70%, or more of the total width W_(J3) of theT-shaped joint 10. In the illustrated embodiment of FIG. 4 , inparticular, the width W_(J3) of the vertical joint portion 2 accountsfor about 50% of the of the total width W_(J1) of the T-shaped joint 10.

Additionally, the height of the T-shaped joint 10 may be minimized suchthat the height of the corresponding hole 82 in the pool liner 8 may beminimized. For example, the total height H_(J) of the T-shaped joint 10may be about 3 inches to about 5 inches, specifically about 3⅞ inches.Because the pin 43 of the coupling assembly 4 may be accessible in frontof the pool liner 8 and behind the T-shaped joint 10, the hole 82 in thepool liner 8 need not extend downward beneath the pin 43. Thus, in theillustrated embodiment of FIG. 4 , the height H_(L) of the hole 82 inthe pool liner 8 is less than the total height H_(J) of the T-shapedjoint 10 while still allowing access to the pin 33 of the couplingassembly 3 and the pin 43 of the coupling assembly 4 for subsequentdisassembly.
